Risk management

A sustainable approach to integrated pest management

There is more scrutiny today than ever before regarding conventional herbicides, fungicides and insecticides, and regulations are tightening. “Complete replacement of synthetic chemistries is impractical,” said Nicholas Body, Alltech Crop Science (ACS) European technical manager. “The future of integrated pest management (IPM) programmes will include the best tactics from a variety of approaches, including nutritional and natural technologies, allowing the producers to reduce inputs while maintaining crop quality and improving sustainability measures.“ With today’s global trend among retailers to be very strict on chemical residues, building the best programme, including all type of technologies, is mandatory. “The use of predictive tools, such as disease models, and preventative, such as elicitors of natural defences, allows us to increase the quality of harvest with only a minimal use of conventional pesticides,” said Body. A balanced nutritional programme is a vital component of an effective IPM programme. “An unhealthy plant, from a nutritional standpoint, is not able to defend itself against a potential pathogen attack,” said Body. Healthy plants have a better chance of resisting disease pressures, and bioavailable micronutrients can support plants’ inherent defences. “If you trick a plant into thinking it’s going to be attacked, then the plant can develop its own metabolic pathways to fight the disease,” Body explained. However, plants are not naturally proactive. “They are reactive organisms,” continued Nicolas Body. “Something must trigger a reaction in a plant to be defensive, unlike an immune system that can react on its own. By using biologicals, such as nutritionals and activators, we can elicit a response in the plant.” Efficient crop management is moving towards a more proactive management of inputs. “We’ve been taught to scout fields, find what’s wrong and then fix it,” said Nicolas Body. “We’re moving to a new perspective where we can act on plant and soil health instead of acting on disease.” Better nutrient management, especially nitrogen, is a key component of this movement and is crucial to sustainability. The focus is to reduce the amount of fertiliser applied to fields and hopefully improve the environment by minimising the application of excess nitrogen. Many European farmers are faced with soils that have been depleted after many years in production. These cannot always provide a perfect balance between exported nutrients and the input fertilisation. With a loss in organic matter and beneficial microbes, the soil is also losing its capacity to act as a buffer. Fortunately, conservative and regenerative approaches to soil management are on the rise, and most farmers are implementing these techniques. Body agrees that a total-system approach will serve crop farmers best in the future. “We continue to research how and when to use biologicals — whether it’s natural activators, foliar micronutrients, natural inoculants or biofungicides — with conventional methods in cropping systems to help producers with environmental stewardship,” he explained. “As any market progresses, we see increasing management of smaller and smaller pieces of the total system.” Source - https://www.freshplaza.com


Kenya - Insurtech startup raises $6M Series A to derisk smallholder farmers

Pula, a Kenyan insurtech startup that specialises in digital and agricultural insurance to derisk millions of smallholder farmers across Africa, has closed a Series A investment of $6 million. The round was led by Pan-African early-stage venture capital firm,  TLcom Capital, with participation from nonprofit Women’s World Banking. The raise comes after Pula closed $1 million in seed investment from Rocher Participations with support from Accion Venture Lab, Omidyar Network and several angel investors in 2018. Founded by Rose Goslinga and Thomas Njeru in 2015, Pula delivers agricultural insurance and digital products to help smallholder farmers navigate climate risks, improve their farming practices and bolster their incomes over time. Agriculture insurance has traditionally relied on farm business. In the U.S. or Europe with typically large farms, an average insurance premium is $1,000. But in Africa, where smallholding or small-scale farms are the norms, the number stands at an average of $4. It is particularly telling that the value of agricultural insurance premiums in Africa represents less than 1 percent of the world’s total when the continent has 17 percent of the world’s arable land. This disparity stems from the fact that the traditional method of calculating insurance through farm visits is often unaffordable for these smallholder farmers. Thus, they are often neglected from financial protection against climate risks like flood, drought, pestilence and hail. Pula is solving this problem by using technology and data. Through its Area Yield Index Insurance product, the insurtech startup leverages machine learning, crop cuts experiments and data points relating to weather patterns and farmer losses, to build products that cater to various risks. But getting farmers on board has never been easy, Goslinga told TechCrunch. According to her, Pula has understood not to sell insurance directly to small-scale farmers, because they can suffer from optimism bias. “Some think a climate disaster wouldn’t hit their farms for a particular season; hence, they don’t ask for insurance initially. But if they witness any of these climate risks during the season, they would want to get insurance, which is counterproductive to Pula,” said the founder in a phone call. So the startup instead partners with banks. Banks provide loans to farmers and make it compulsory for them to have insurance. With the loan, banks can pay the insurance on behalf of the farmers at the start of the season. But at the end of the season, the farmer has to repay the loan with interest. “The unit economics doesn’t work for us to work with farmers directly. But with banks, we know they provide loans to farmers with much better margins to pay for insurance. Also, we work together with government subsidy programs since they’re also interested in protecting their farmers.” Through its partnerships with banks, governments and agricultural input companies, Pula is at the center of an ecosystem that provides insurance to smallholder farmers and has amassed 50 insurance partners and six reinsurance partners. Its clientele includes the likes of the World Food Programme and Central Bank of Nigeria as well as the Zambian and Kenyan governments. Social enterprises like One Acre Fund, startups like Apollo Agriculture, and agribusiness giants like Flour Mills and Export Trading Group are also among Pula’s clients. Co-CEOs with agricultural backgrounds When Goslinga met Njeru in 2008, she worked for Syngenta Foundation for Sustainable Agriculture (SFSA). There, she started Kilimo Salama, as a micro-insurance program for more than 200,000 farmers in Kenya and Rwanda. She met Njeru who was the lead actuary at UAP Insurance, a partner to the Kilimo Salama program, at the time. After staying with Syngenta for six years and recognising the need to provide standard insurance products for smallholder farmers, Goslinga left to start Pula with Njeru in 2015. However, it wasn’t until two years later that Njeru joined fulltime as he had a six-year engagement with Deloitte South Africa from 2012 as a consultant actuary. The pair both act as co-CEOs. “When Thomas and I launched Pula in 2015, we had one goal in mind: to build and deliver scalable insurance solutions for Africa’s 700 million smallholder farmers,” Goslinga said. “With our latest funding, now is the time to break into new ground. In our five years since launching, we’ve built strong traction for our products. However, the fact remains that across Africa and other emerging markets, there are still millions of smallholder farmers with risks to their livelihoods that have not been covered.” According to Goslinga, the COVID-19 pandemic helped Pula double its footprint and size as rural farming activities and operations continued despite pandemic-induced lockdowns. Therefore, the new financing will scale up operations in its existing 13 markets across Africa, where it has insured over 4.3 million farmers. They include Senegal, Ghana, Mali, Nigeria, Ethiopia, Madagascar, Tanzania, Kenya, Rwanda, Uganda, Zambia, Malawi and Mozambique. Likewise, the Kenyan startup hopes to propel its expansion for smallholder farmers in Asia and Latin America. Pula is one of the few African startups disrupting the farming industry with technology. Its Series A investment attests that investors’ appetite for agritech startups is still on the rise. A week ago, Aerobotics, a South African startup that uses artificial intelligence to help farmers protect their trees and fruits from risks, raised a Series B round of $17 million. Last month, SunCulture, a Kenyan startup that provides solar power systems, water pumps and irrigation systems for small-scale farmers, raised $14 million. Another startup is Apollo Agriculture which raised $6 million Series A, akin to Pula. Not only did the pair raise the same round, Apollo Agriculture and Pula both deal with providing financial resources to smallholder farmers. But while both companies might look like competitors, even to the admission of Goslinga, she argues that the startups are partners and complement each other. As part of the new fundraise, TLcom’s senior partner Omobola Johnson will join Pula’s board. However, it was her colleague, Maurizio Caio, the firm’s managing partner, who had something to say about the round. “The potential for the insurance market for smallholder farmers in Africa is huge, and under the leadership of Rose and Thomas, Pula has rapidly established a strong presence throughout the continent and has several high-profile clients on their books. We are confident of Pula’s potential for growth in spite of the pandemic and look forward to partnering with them as they execute the next phase of their journey,” he said in a statement. For the lead investor, Pula’s investment marks the culmination of its busiest run of investments having led and co-led rounds in Okra, Shara, Autochek and Ilara Health within the past year. Christina Juhasz, CIO at Women’s World Banking, the other investor in the round, explained that the organisation cut a check for Pula “given the legions of women engaged in small-hold farming and securing the food supply for communities around the globe.” Source - https://techcrunch.com


Africa - Advances in modeling and sensors can help farmers and insurers manage risk

When drought caused devastating crop losses in Malawi in 2015-2016, farmers in the southeastern African nation did not initially fear for the worst: the government had purchased insurance for such a calamity. But millions of farmers remained unpaid for months because the insurer's model failed to detect the extent of the losses, and a subsequent model audit moved slowly. Quicker payments would have greatly reduced the shockwaves that rippled across the landlocked country. While the insurers fixed the issues resulting in that error, the incident remains a cautionary tale about the potential failures of agricultural index insurance, which seeks to help protect the livelihoods of millions of smallholder farmers across the globe. Recent advances in crop modeling and remote sensing—especially in the availability and use of high-resolution imagery from satellites that can pinpoint individual fields—is one tool insurers that can help improve the quality of index insurance for farmers, report a team of economists and earth system scientists this week in Nature Reviews Earth & Environment. "The enthusiasm for agricultural insurance needs to be matched with an equally well-founded concern for making sure that novel insurance products perform and help, not hurt, farmers exposed to severe risk," said Elinor Benami, the lead social scientist of the review. The review was co-led by Benami, an assistant professor in Agricultural and Applied Economics from Virginia Tech, and Zhenong Jin, an assistant professor of Digital Agriculture at the University of Minnesota, and included Aniruddha Ghosh from the Alliance of Bioversity International and CIAT. The authors outline opportunities for enhancing the quality of index insurance programs to increase the value that index insurance programs offer to agricultural households and communities. "Improvements in earth observation are enabling new approaches to assess agricultural losses, such as those resulting from adverse weather," said Zhenong. Index insurance in agriculture triggers payments when certain environmental conditions—seasonal rainfall, for example—stray from thresholds for a typical harvest. Unlike policies that require costly and time-consuming field visits to assess claims, index insurance uses an indicator of losses to cover a group of farmers within a given geographical area. This approach offers the promise of inexpensive, quick coverage to many people who would otherwise be uninsured. Lack of other types of coverage is due, in part, to the cost involved in verifying small claims on the ground. As the Malawi case shows, verification is also an issue for index insurance but its potential for scale, speed, and low cost render it viable for both insurers and desirable for farmers. When well matched to local experiences, index insurance can have meaningful impacts on agricultural livelihoods. One study cited by the authors found that people insured under a Kenyan index insurance program reduced their "painful coping strategies" by 40-80% when compared to uninsured households. In non-technical terms, "painful coping strategies" for smallholder households include skipping meals, removing children from school, and selling off what little productive assets they have. "Shocks that destroy incomes and assets have been shown to have irreversible consequences," said Michael Carter, a co-author of the review and an agricultural economist at the University of California, Davis. "Families never recover from the losses and become trapped in poverty. By restoring assets and income destroyed by shocks, insurance can halt this downward spiral before it starts. This can fundamentally alter the dynamics of poverty." Insurance has been shown to push the poverty needle in the other direction. By protecting assets after bad seasons, insurance payments also build the confidence farmers have to invest in their farms and progress toward better wellbeing, secure in the knowledge they will not need to pursue painful coping if bad times fall. Despite a few decades of experimentation with the idea of index insurance, however, serious quality issues have plagued implementation on the ground and place the otherwise promising concept of index insurance itself at risk. "With the technology of remote sensing changing rapidly, we wrote this review to call attention to the quality problem and to highlight ways to harness those technological advances to solve that problem. Our immodest hope is that this article will make more, high-quality insurance products available to small-scale farmers across the globe," said Carter. Better models, coverage Governments and insurers in sub-Saharan Africa have enrolled millions of farmers in index insurance programs. Programs have met with varying degrees of success and generally focus on livestock, in part because weather-related losses on rangelands are relatively easier to quantify. The authors say enhanced satellite imaging can potentially increase coverage and include more cropland. But improving the effectiveness of insurance is a bigger goal. "We're trying to encourage the insurance community to move towards not just how many people you have enrolled but how many people you protected well when they suffered," said Benami. To that end, the researchers discuss a minimum quality standard in their review, which is akin to a medical doctor's oath to patients: A minimum quality standard is based on the premise of doing no harm to farmers. Poor insurance coverage can make farmers worse off than they otherwise would have been without insurance. "The criteria that insurance regulators have told us that they want is good value for money—meaning that farmers get effective risk reduction and asset protection for the premia that are paid," said Benami. "As we understand it, insurers are looking for ways to reduce cost and encourage uptake while meeting regulatory requirements for their roll-out." To improve the quality, reliability, affordability and accessibility of index insurance, the authors make five concrete recommendations in their study. First, the full potential of higher-resolution spatial data and new data products on environmental conditions should be explored. Many possibilities exist to wring more value from satellite data for index insurance—such as pairing data from multiple sensors and or with crop models—and examining those possibilities is a promising opportunity to improve the match between observation and experience on the ground. Second, several opportunities exist to help improve loss detection. For example, this can be done with better crop modeling and new data products enabled by remote sensing, such as higher resolution soil moisture indicators of 100-meter resolution. Additional data sources such as drones and smartphones can be incorporated. Insurers should focus on metrics of farmer welfare as the key objective in insurance design. Third, better on-the-ground data will help bolster the usefulness and quality of insurance programs. Ground-referenced data is essential to evaluate how well a given index relates to a farmer's reality, and strategically collected data on environmental conditions, crop types, and yields for the areas considered by insurance would help diagnose and improve insurance quality. Fourth, insurance zones can be optimized to better reflect the geographic, microclimatic, and crop-management conditions that influence the productivity of specific landscapes. Within large administrative boundaries, considerable variation can occur due to mountains, rivers and different social customs. Finally, contracts can be designed to accommodate a variety of needs and the inevitability of index failure. Farmers have different needs and a rigid insurance contract window may not always reflect the times of the year a farmer is most concerned about risk as it relates to their production strategies and location. In addition, secondary mechanisms—liked audits—can be put into place to minimize uncompensated losses that can be missed by index errors. In implementing these recommendations, the Alliance's Ani Ghosh notes the importance of interdisciplinary, researcher-practitioner collaborations. For example, "the advances in economic, remote sensing, and crop modeling led by academic institutions complement CGIAR's experience in targeting, prioritizing, and scaling out interventions for smallholder farmers that can maximize the impact of index insurance programs," Ghosh said. "Overall, evaluating and designing programs to successfully manage risk is a problem with both technical and social dimensions," the authors conclude. "Although index insurance instruments will not solve all agricultural risk-related problems, they offer a useful form of protection against severe, community-wide shocks when done well."

Understanding disease-induced microbial shifts may reveal new crop management strategies

While humanity is facing the COVID-19 pandemic, the citrus industry is trying to manage its own devastating disease, Huanglongbing (HLB), also known as citrus greening disease. HLB is the most destructive citrus disease in the world. In the past decade, the disease has annihilated the Florida citrus industry, reducing orange production for juice and other products by 72%. Candidatus Liberibacter asiaticus (CLas) is the microbe associated with the disease. It resides in the phloem of the tree and, like many plant pathogens, is transmitted by insects during feeding events. Disease progression can be slow but catastrophic. Symptoms begin with blotchy leaves, yellow shoots, and stunting, and progress into yield decline, poor quality fruit, and eventually death. Currently, the only thing citrus growers can do to protect their crops from HLB is control the insect vector. Dozens of researchers are trying to find ways to manage the disease, using strategies ranging from pesticides to antibiotics to CLas-sniffing dogs. Understanding the plant microbiome, an exciting new frontier in plant disease management, is another strategy. Dr. Caroline Roper and first author Dr. Nichole Ginnan at the University of California, Riverside led a large research collaboration that sought to explore the microbiome's role in HLB disease progression. Their recent article in Phytobiomes Journal, "Disease-Induced Microbial Shifts in Citrus Indicate Microbiome-Derived Responses to Huanglongbing," moves beyond the single-snapshot view of the microbial landscape typical of microbiome research. Their holistic approach to studying plant-microbe interactions captured several snapshots across three years and three distinct tissue types (roots, stems, and leaves). What is so interesting about this research is the use of amplicon (16S and ITS) sequencing to capture the highly intricate and dynamic role of the microbiome (both bacterial and fungal) as it changes over the course of HLB disease progression. Ginnan et al. surmised that HLB created a diseased-induced shift of the tree's microbiome. Specifically, the researchers showed that as the disease progresses, the microbial diversity increases. They further investigated this trend to find that the increase in diversity was associated with an increase in putative pathogenic (disease-causing) and saprophytic (dead tissue-feeding) microbes. They observed a significant drop in beneficial microbes in the early phases of the disease. Arbuscular mycorrhizal fungi (AMF) were one such beneficial group that the authors highlighted as showing a drastic decline in relative abundance. The depletion of key microbial species during disease might be opening the door for other microbes to invade. Certain resources may become more or less available, allowing different microbes to prosper. Dr. Roper and Dr. Ginnan hypothesize that when HLB begins, this depletion event triggers a surge of beneficial microbes to come to the aid of the citrus tree. They suspect that the microbes are initiating an immune response to protect the host. As the disease proliferates, the citrus tree and its microbiome continue to change. Dr. Ginnan, the lead author on this study, found that there was an enrichment of parasitic and saprophytic microorganisms in severely diseased roots. The enrichment of these microbes may contribute to disease progression and root decline, one side effect of HLB. Survivor trees, or trees that did not progress into severe disease, had a unique microbial profile as well. These trees were enriched with putative symbiotic microbes like Lactobacillussp. and Aureobasidium sp. This discovery led the researchers to identify certain microbes that were associated with slower disease progression. Dr. Ginnan says their "aha" moment during the research was in the data analysis. "Originally we were looking for taxa that increased and decreased in relative abundance as disease rating increased," she said. "Our differential abundance analysis ended up revealing clear enrichment patterns replicated in multiple taxa." This is the moment they began to develop the individual patterns they were seeing into a broader disease model. This research is the foundation for future projects and collaborations that the authors are excited to continue to develop. They are motivated by the potential function of the microbiome to manage crop diseases. In the near future, they hope that these discoveries and an understanding of beneficial microbes can help establish a microbiome-mediated treatment plan to protect crops from diseases like HLB. In addition, the model they've developed can be applied to understanding diseases of other tree crop systems. Source - https://www.eurekalert.org


Canada - Sask. anticipates spending less on business risk programs

The Saskatchewan budget scheduled for March 18 turned out to be a non-event as the Legislature shut down amid COVID-19 concerns. Earlier that day the government announced a spending plan of $14.15 billion, but couldn’t say how much the virus will cost the health system or how much revenue the province could expect to take in. Finance minister Donna Harpauer said the province has access to $1.3 billion in cash if needed. Premier Scott Moe said the government would provide the funding needed to fight the pandemic. Cabinet will require special warrants to get money out of the door. Of the total, the agriculture ministry will see spending drop by $22 million or almost six percent to nearly $369 million. The major decrease comes in business risk management spending, which is always based on federal forecasts. The estimates project $15.8 million less spending for AgriStability and $15.9 million less on crop insurance premiums. Agriculture Minister David Marit said the federal forecasts were done in December. “It is important to note that business risk management spending is government by federal-provincial agreements and the amount that we spend in any one year is impacted by commodity prices and program participation,” he said through an emailed statement. “We recognize that the markets are very volatile and those spending forecasts will be adjusted through the year.” One area that will see some additional spending is irrigation development. Marit said $5 million will be used to conduct additional analysis of the potential, including a study of the Westside Irrigation and Qu’Appelle South Irrigation projects. Part of that work will include land identification and soil suitability assessments. “It is too early to indicate the costs required to build irrigation infrastructure,” he said. Marit added that investment from the federal government and the private sector would be required to develop the infrastructure. Source - https://www.producer.com


Managing frost damage on late-season corn for silage

Late corn plantings and cool autumn temperatures create a recipe for frost damage on corn grown for silage. The extent of the frost damage on the corn depends on the temperature, duration of the temperature, and corn growth stage at the time of the frost. Conditions for a frost Air temperatures below 32°F for four to five hours will result in frost damage to the stalk, leaf, and husk. Air temperatures that drop to 28°F for a few minutes and return to 32°F can result in similar injury. Air temperatures between 32°F and 40°F typically result in less frost damage. Frost at temperatures above 32°F usually occurs under conditions of clear skies, low humidity, and no wind. These conditions are ideal for rapid heat loss from the corn leaves. Under these conditions, temperature of the corn leaves can be less than the air temperature. Thin stands of corn and corn stands at the edges of fields are more likely to receive frost damage at temperatures above 32°F than thicker stands and the centers of fields. The uppermost leaves of the corn plant are most susceptible to frost damage at temperatures between 32°F and 40°F. Growth stage at time of frost Management of corn damaged by frost will depend on the stage of growth at the time of frost. Corn will ensile well at moisture levels less than 70% for upright silos and less than 75% moisture for horizontal silos. Corn harvested at 62% to 68% moisture (late-dent stage) is ideal for ensiling. Frost damage prior to the late-dent stage will result in corn that is too moist for silage harvest. Frost at these higher moistures will reduce yields and may reduce quality. Management of corn damaged by frost will depend on the stage of growth at the time of frost. (Photo: Courtesy of University Kentucky) Corn moisture content can be determined with a microwave or forage moisture tester. A simple field technique for determining corn moisture content is to squeeze a ball of chopped corn forage in your hand for 30 seconds. Release the ball of chopped forage and examine its shape. You can gain a rough estimate of moisture content based on the descriptions in Table 2. If you would prefer to not use the silage chopper to help determine whole plant moisture, then you can use a tobacco or corn knife to chop several corn plants. Be careful to chop up the corn plants into pieces that are similar in size to those cut by the silage chopper. Frost at Milk Stage When a frost occurs on corn at the milk stage, the moisture content of the plant is too high for proper ensiling. The leaves of the plant will dry very quickly, which causes the entire plant to appear to be drying more quickly. However, the entire plant will dry down similarly to corn that was not injured by frost. If the corn at milk stage is ensiled immediately after frost, then nutrients will leach away, the silage will be sour and wet, and livestock consumption will be low. Waiting to harvest frost-damaged corn at the milk stage will improve silage quality but will decrease dry matter yield. Up to 10% dry matter losses will occur the first 10 days after the frost, and up to 20% dry matter will be lost 40 days after the frost. In addition, mold may develop in the ears and cause further yield reductions. Because of these factors, a compromise between dry matter yield and ideal ensiling moisture must be made. In some cases, the corn will need to be harvested when it is too wet for silage. In these situations, chopped grain, hay, or straw can be added to the silage to decrease overall moisture. In general, 30 pounds of dry matter per ton of silage are required to reduce the moisture percentage by one point. For example, if the corn was at 78% moisture and the target moisture was 68%, then 300 pounds of dry matter would be required for each fresh ton of silage. One concern of frost occurring at the milk stage is high nitrate levels. High nitrate levels are toxic to cattle and will occur most frequently when the corn has been under drought stress prior to the frost. Ensiling will reduce nitrate levels 40% to 60%. To reduce the risk of nitrate toxicity, allow the ensiling process to occur for at least 21 days before feeding. See ID-86, Using Drought-Stressed Corn: Harvesting, Storage, Feeding, Pricing, and Marketing, for more information on nitrate levels in corn. Another option for corn with high moisture content is to feed the corn as green-chop. Cattle will consume less green-chop corn than ensiled corn. However, the quality of the frost-damaged, green-chopped corn is better than the quality of the ensiled corn at milk stage. If the corn is to be fed as green-chop, then check the corn for nitrate levels before feeding. A diagnostic test is available for determining nitrate levels, which is usually available through your county Extension office. Frost at Dough Stage If a frost occurs when the corn is at the dough stage, then whole corn is often too wet for silage harvest. Typically, several drying days are necessary before whole corn will be at the proper moisture for silage harvest. The corn should be harvested as soon as it reaches the desired moisture of 70% to 75%. The balance between waiting to harvest corn for silage at the ideal moisture and harvesting to prevent yield loss still must be considered. However, corn damaged by frost during the dough stage will require less time to dry down than corn damaged during the milk stage. If a frost occurs when corn is at the early dent stage, then whole corn may need to dry a couple days before it is ready to harvest. (Photo: Colleen Kottke/Wisconsin State Farmer) Frost at the Dent Stage If a frost occurs when corn is at the early dent stage, then whole corn may need to dry a couple days before it is ready to harvest. If a frost occurs when the corn is at the mid- to latedent stage, whole corn is at or very close to ideal moistures for ensiling. Corn damaged by frost at the mid- to late-dent stage should be harvested for silage immediately because whole plant moisture should be close to ideal for harvest and waiting to harvest could cause yield reductions. Summary Management of frost damage to corn grown for silage depends in part on the stage of growth when the frost occurred. Corn in the milk and dough stages is too wet for chopping and ensiling. The corn plants need to dry down before chopping occurs. Waiting to harvest frost-damaged corn will improve silage quality but will decrease dry matter yield. Producers must balance between expected yield losses and quality gains by waiting to harvest. Source - https://www.wisfarmer.com


New Zealand - Fans get to work as spring frosts threaten precious grapes

Vineyard frost fans have been doing their bit to protect one of Marlborough's biggest money spinners after a few cold starts in October. The fans, which pull warm air down onto the vines, are used when grapes start to bud - as a spring frost can lead to crop loss. Blenheim experienced four frosts in the first week of October, while all of October 2018 had only two frosts. But Marlborough Plant and Food research scientist Rob Agnew suspected frost fans would have been used more out in the Wairau Valley because of its colder climate. Villa Maria viticulturist Stuart Dudley said because Marlborough was a cool climate viticulture region there were definitely areas that were exposed to spring and autumn frosts. "The fans work by effectively bringing down warmer air," Dudley said. "It's called an inversion layer, effectively it's the same principle that is used by helicopters to protect the crops, but wind machines are a lot more reliable. "For us, as viticulturists, the wind machines are great, because if you get a forecast saying it might get to zero [degrees Celsius] and then you would have to toss up whether to spend the money on helicopters or not, whereas if you've got a frost fan the decision is already made, you just have to flick it on." Most were automatic, with a start temperature just above zero, but some grapegrowers had started switching from two-bladed fans to four or five, which were quieter, Dudley said. A Neighbourly poll showed 50 per cent of respondents who lived next to a vineyard were used to the sound. However, 17.3 per cent of respondents said they struggled to sleep at night because of the sound. Hawkesbury resident Nigel Taylor said noise from frost fans was something "you get used to". "You hear the two-bladed ones more than those with four or five," Taylor said. "You can definitely hear them but they don't interrupt us, you learn to live with it. "They're temperature-controlled so you notice when they turn off too, it's not a major disruption." Jenny King said rural residents knew living next to a vineyard could come with some noisy nights. "It's a small price to pay," King said. "It doesn't make for a great mood the next day but it's one of those things." King said she tended to hear the helicopter from the cherry orchards in Springlands more. Marlborough resident Ben Wallace said the fans were "minimally disruptive". "The benefits of frost fans for the local economy far outweigh the noise you have to put up with," he said. Source - https://www.stuff.co.nz


USA - Northern NY apple research tests hail netting as pest management[:ru]US

Real-time, regional, in-orchard research funded by the Northern New York Agricultural Development Program is helping apple growers quickly respond to pests with the latest management practices, the organization said. "Pest management is one of the largest investments fruit growers must make in terms of time, labor, and materials to produce marketable fruit and maintain healthy trees," says Michael Basedow, a tree fruit specialist with the Cornell Cooperative Extension Eastern NY Commercial Horticulture Program, Plattsburgh, N.Y. With a grant from the Northern New York Agricultural Development Program, Basedow provided weekly pest scouting data to help growers quickly respond to orchard pests with appropriate pest management tactics. He also initiated a project to evaluate whether exclusion netting used for protecting apple from hailstorm damage might also protect the fruit from orchard pests. A series of hailstorms in 2017 damaged the regional apple crop. One grower reported more than 60 percent of his acres suffered damage. Basedow says, "Growers selling hail-damaged fruit for juice that would otherwise have sold at retail prices can see as much as a 98 percent decrease in the economic value of their crop." Basedow worked with commercial growers in Clinton and Essex counties who had installed hail netting. Trials in France and Quebec, Canada, had shown success in limiting damage by codling moth and other orchard pests, but the use of drape-style netting had not been well-evaluated under northern NY orchard conditions.

Galimberti, CCE Clinton County, NY "We are constantly looking at ways to increase the use of integrated pest management practices that allow us to produce a commercially viable crop while also making the best use of growers' time, labor, and money. We wanted to see if the hail netting might be an effective practice to add to our apple growers' IPM toolbox," Basedow said. The research provided weekly trap data on four key apple pests in northern NY: codling moth, Oriental fruit moth, obliquebanded leafrooler, and apple maggot. "Results from the trial showed that traps in the trees under the netting caught significantly fewer of the four key pests compared to the unnetted trees, however," Basedow says, "the pest pressure levels in 2018 for three of the four key pests was such that the feasibility of using hail netting for pest exclusion is still uncertain. The netting may help reduce pest numbers enough to reduce the total number of orchard sprays needed for some pests, such as apple maggot, where spray decisions are based on well-established economic thresholds." Basedow adds that the sites with the most effective pest exclusion were those where the hail netting was tightly tied to the lower limbs and trunks of the apple trees. The orchard with the best control applied the netting to trees grown to a tall spindle training system with the netting secured tightly to the trunks. Source - https://www.freshplaza.com


Canada - Moisture kick-starts canola spray discussions

The decision whether to spray for sclerotinia stem rot in canola begins with a moisture assessment about three weeks before flowering. The situation before that point is almost irrelevant, given the canola plant’s ability to crank up yield potential in response to improved growing conditions. Sclerotinia stem rot can go from no risk to high risk with a timely period of regular rains and humidity. Moisture before flowering will result in the emergence of spore-producing apothecia. Under ideal warm and moist conditions, it takes around three weeks for sclerotia to germinate and release ascospores. Moisture during flowering will enable ascospores to infect canola petals and grow into leaf and stem tissues when the infected petals fall into the crop canopy. Spraying after flowering or after symptoms have appeared on the plant is too late, so the decision has to be based on the risk situation before and during the spray window — which is 20 to 50 per cent flower — and the forecast of weather and yield to come. Risk of economic levels of sclerotinia stem rot increases with the following: • A wet soil surface underneath the canola canopy for most or all of the day. This promotes germination of sclerotia and production of apothecia, the tiny mushrooms that release sclerotinia spores. • The presence of apothecia, which are a sign that spores will be present. Other options for spore detection are the Spornado (from 20/20 Seed Labs) or DNA-based petal tests (from Quantum Genetix and Discovery Seed Labs). • Higher yield situations. Yields are difficult to predict, so a better indicator may be a canopy dense enough to create the humid microclimate that favours disease. If you walk through the canopy in early afternoon and your pants get wet, the field has favourable conditions for infection. • Moderate average temperatures of 15-25°C and moderate rainfall that favour host infection while extending the bloom period and reducing sloughing off of leaves, thus maintaining potential infection sites. • Extensive sticking/clumping of petals in the crop canopy, especially in the leaf axils and bases. • A history of significant levels of sclerotinia in the specific field or in adjacent fields. Host crops include canola, soybeans, sunflowers, potatoes and pulses. Risk of economic levels of sclerotinia stem rot decreases with the following: • Dry conditions through the flowering period. • A poor canola canopy that allows for a lot of air flow. When doing the wet pants test, if the canopy and your pants and boots are dry at 8-10 a.m., then the field has less favourable conditions for the disease. • Well below- or above-average temperatures (less than 10°C or more than 25-30°C) and limited rainfall. • A large rainfall event over one or two days that is followed by several days of dry, warm conditions. • Continuous rain events that may lead to washing off of petals from plants and remove spores from the air, while trapping spores in water droplets that form on the tops of the apothecia. Note that a moisture situation like this that actually reduces sclerotinia stem rot risk would be unusual. Management approaches if the potential for disease is uncertain include: • Apply the lowest rate of fungicide. Use programs or lowest-cost products to keep costs as low as possible. • Always use highest label water rates to get the most coverage and best efficacy. • If perked-up fields are to rebound and achieve target yields, they will likely have to branch out and flower for longer. In this situation, “full flower” (50 per cent flower) could last a week or more. This can be an effective time to spray, especially in a situation where moisture changed dramatically for the good and the crop canopy is slowly filling in. Farmers in this situation may choose to wait a little longer to assess crop recovery before making the spray decision. • Generally, early infections cause more yield loss than later infections, which is why the economic benefit of a fungicide application is usually higher with early applications. • Consider an “on-off” or zone-spraying approach, basing it on previous yield maps or current NDVI maps. Fungicide application could be turned “on” for areas with high yield potential and “off” for typically low-yielding areas • If you need to spray so you can sleep at night, then spray. But leave a few test strips to compare disease amounts and yield. This can help with future decisions. Conditions where a grower may want to spray more than once include: • Variable crop staging that extends the flowering period. • Thin stands mean branchier plants and an extended flowering period. • Note that continued rain throughout flowering will add to the yield-loss risk for the first two scenarios. • Regrowth after a hail. • In any of these situations, assess yield potential and crop stage relative to the calendar when pencilling out the potential return on investment.

Australia - Weather certificates provide affordable risk management

In recent decades, numerous weather and climate-related natural disasters have impacted agriculture across the globe, repeatedly demonstrating how vulnerable the industry is too extreme episodic events. Some research suggests that up to 70 per cent of agricultural risk is related to weather. Given this recent history, and expectations that the frequency and intensity of such events will increase with climate change, it is becoming increasingly important for farmers to proactively manage weather and climate risks in order to farm sustainably and protect their livelihoods. Droughts, floods, cyclones, hurricanes, bushfires, heat waves, freezes, wind, frost and localised thunderstorms are some of the challenges facing agricultural production and food security in the world today. Local variables such as latitude, elevation, and proximity to water also have a significant influence on the weather and climate at individual locations. It is often reported that Australian farmers operate in one of the riskiest climatic environments on the planet. While farming businesses face many sources of risk, the unpredictability of Australian weather is probably the most difficult of them to manage. And any decrease in income at the farm level has a downstream flow on effect to the entire rural economy. Some farmers already apply a variety of strategies to help reduce the impact of weather uncertainties. These include farming in multiple locations to spread the exposure geographically, minimum tillage and chemical fallow practices to conserve moisture, diversifying crop types and varieties, spreading the planting period to minimise frost risk, seeking alternative sources of income, and purchasing crop insurance. Other farmers, however, have failed to adopt basic risk management tactics despite the clear benefits. Reasons for these failures can be attributed to the cost of adapting the farm business, inadequate farmer education and training, a lack of tools to help facilitate the practical application of risk management concepts, and poor communications between the farming and meteorological communities. There is no greater reminder of the threat to domestic agriculture than the drought experienced in the eastern states of Australia last season. Grain production was impacted to such an extent that the east coast turned from a net exporter to a net importer of grain to satisfy domestic demand. That drought is yet to break in many regions and is threatening to severely impact production again in 2019. So how can grain growers manage the most significant risk to their business? One weather risk management tool increasing in popularity in Australian agriculture are weather certificates (sometimes called weather derivatives). They are relatively simple products that hedge against the risk of weather-related losses. They are based on an index representing a single variable, such as temperature or rainfall. Some research suggests that up to 70 per cent of agricultural risk is related to weather.- Grain Brokers Australia They are basically financial options that can be used to transfer some of the risks associated with weather variability away from the grain producer and local community and onto financial organisations that specialise in managing and trading risk and have the balance sheet capacity to absorb any loss. Grain Weather Certificates allow the buyer to establish their weather risk versus their input investment and potential returns relative to the growing season. They can provide income protection against weather conditions such as a dry season, a wet season, temperature extremes such as frost at flowering, extreme heat at critical stages of crop growth, hail or excessive rainfall at harvest. One of the big advantages of weather certificates is that they can be tailored to meet the individual growers' risks and requirements in the course of a season. Conversely, crop insurance is a generic product that doesn't consider individual needs or geographic anomalies. Insurance tends to cover low-probability, catastrophic weather whereas derivatives can cover the buyer for higher-probability region-specific events. For example, a grower may wish to protect against an abnormally dry season. The weather certificate would payout if the in crop rainfall was below a pre-specified amount over a pre-specified time period. On the flip side, a farmer may wish to protect against the possibility of quality downgrading at harvest due to rain. The weather derivative would payout if rainfall was above a pre-specified amount over a pre-specified time period. And unlike crop insurance, no demonstration of loss is required, and no assessment needs to be made. Once the event has occurred payout of a weather certificate is automatic. It is based on a weather index which is derived from readings at the Bureau of Meteorology weather station nominated when the weather certificate is purchased. This is usually the weather station closest to the grower's property, as long as there is sufficient historical data to establish an index. The cost of weather certificates has also been decreasing relative to crop insurance in recent years as their adoption increases across a variety of Australian industries. It is generally between 7.5 per cent and 10 per cent of the value the buyer wishes to protect. The price will vary slightly by region depending on the likelihood of the nominated event occurring. With the incidence of extreme weather events increasing and margins getting squeezed by rising input costs, farmers need to look at all options available to decrease exposure to the most significant risk they face each season. Weather certificates provide a transparent, easy and cost-effective option to help Australian grain growers protect their livelihood against the vagaries of climate variability and extremes.

South America - New parametric reef insurance & resilience product to be developed

A new initiative to develop a parametric insurance product to protect and enhance the resilience of coral reefs and the communities that rely on them is being developed by Willis Towers Watson through its Global Ecosystem Resilience Facility (GERF) and the Mesoamerican Reef Fund (MAR Fund). An agreement has been reached that will see the pair working on an insurance and risk transfer model for coral reefs specifically for the four countries of the MAR Region; Mexico, Belize, Guatemala and Honduras. A concept for the project has been submitted to the InsuResilience Solutions Fund, which is part of the InsuResilience Global Partnership and managed by KfW, the German government-owned development bank. The project will see a parametric insurance model for reefs developed with the specific goals of supporting early response and restoration after climate, weather and catastrophe events. The aim is to reduce long-term damage to coral reefs and speed up their recovery, while improving their resilience and creating a natural capital value in the Mesoamerican Reefs. The parametric reef insurance product is set to be developed and implemented at roughly seven locations across the four countries of the MAR Region. Reefs are a vital part of coastal natural infrastructure and they are at risk globally from weather and climate related catastrophe events. Therefore, providing risk capital to support the resilience and recovery of reefs is aligned with the catastrophe and weather risk focus of ILS and alternative reinsurance markets, while the parametric triggers make for simpler modelling and payout terms. Reefs provide important resources and resilience to local communities, in the way of food security, biodiversity, tourism and coastal infrastructure. The coastal infrastructure aspect also helps to maintain the resilience of coastal communities against storm surge and other flooding events as well, hence creating a natural capital value to the reefs and transferring the natural risks they face to insurance and reinsurance capacity not only supports the reef, but can also lessen coastal losses. While the practical value of reefs has been understood for some time, the ability to model and understand their financial or natural capital value is a more recent development and is now leading to some interesting risk transfer initiatives, such as this one. Willis Towers Watson likens this to current parametric insurance products for crops and cattle, saying that “Insurance for reefs is an innovative financial mechanism that can contribute to reef restoration and recovery.” The broker and adviser launched its Global Ecosystem Resilience Facility last year, hailing it as an insurance facility designed to help strengthen the resilience of ecosystems and their communities through the use of efficient risk transfer and saying that in future catastrophe bonds could feature in its work.

USA - Challenges remain but multi-peril crop re/insurance business still favourable

Despite notable sector headwinds, ratings agency A.M. Best still views both the primary and reinsurance multi-peril crop insurance business as favourable, highlighting the “marriage” between carriers and agricultural focused technology firms as an efficiency driver. In recent times, the U.S. government-subsidised multi-peril crop insurance industry has been under pressure, driven by weather-related losses, commodity price volatility, and also the renegotiated Standard Reinsurance Agreement (SRA). At the same time, and following four years of underwriting losses ending in 2015, the market reported underwriting profitability in both 2016 and 2017, explains A.M. Best, in a recent crop insurance industry note. Historically, explains the rating agency, this line of business has been very profitable, but growth is hindered as a result of high market penetration and potential changes to legislation that drive short-term uncertainty. One such potential change concerns the federal crop insurance program, which is set to expire in September 2018, and which has come under increased scrutiny in recent times. A.M. Best notes certain proposals that have recommended numerous provisions to the program, which includes reducing the target rate of return from 14.5% to 8.9%, as well as limiting subsidies to individual farmers. Furthermore, A.M. Best warns that enforced tariffs could result in significant volatility for crop commodity prices. Volatility, which, has already drove fluctuations in multi-peril crop insurance direct premiums written, explains the ratings agency. Discussing legislation, A.M. Best says: “Although radical reform is unlikely, major cuts could change the landscape for famers and MPCI insurers alike. Despite the legislative uncertainty, the MPCI market is viewed favourably, with its traditional profitability and advancements in agricultural technology counteracting the current headwinds.” Consolidation is another trend impacting the sector, underlined by large insurers absent multi-peril crop business as a way to diversify, while enabling those with multi-peril crop operations to diversify by geography and achieve greater scale, which A.M. Best says is becoming increasingly important in the sector. Reinsurance capacity in the space continues to expand also, and pricing for reinsurance in the market remains favourable, says A.M. Best. Furthermore, reinsurers with excess capacity and experience in the crop market have also looked to acquire approved crop insurance providers, as both primary players and reinsurers look for greater scale. Overall, A.M. Best views the market as favourable for the primary players and the reinsurers, highlighting the utilisation of technology as a driver of efficiency and an improved experience for farmers. “The marriage of insurers and agricultural technology firms also is allowing farmers and insurers to gather more data, optimize yields and customize products. The results are higher yields and greater efficiency for farmers, less risk and lower claims-handling costs for insurers, and more automation for both parties,” explains A.M. Best.

Romania - People warned not to buy vegetables affected by recent floods

Weather conditions are finally improving for Romanian vegetable growers, after a cold and dry start to the season. There were new challenges last week, with rains continuing for 7 days and 7 nights in some regions. Scientists have been warning local consumers to be cautions consuming vegetables affected by the damp conditions because the products could be infected with mould and harmful bacteria. The hardest hit have been tomatoes, raspberries, blueberries and in some cases, the entire melon harvest has been compromised. Damages are the most visible in the market place, where tomatoes and melons are arriving mouldy and cracked. "We are located in the Matca, Romania, where most of the greenhouse production takes place, and we are lucky that everything was ok with our crops here. We have had some yield issues this season with our first cycle and were getting quite low prices, but prices are starting to increase again with the start of the first cycle in another one of our growing regions," shared Valentin Tofan from Marcoser. The tomatoes produced by Marcoser and the local farmers from Matca are primarily for the domestic market. Valentin shared that the market has changed a lot in the last two years, after a market development scheme from the Ministry of Agriculture. "In 2017 and 2018, support was offered to tomato producers, under the conditions that the yield of at least 2 kg/sqm is produced and delivered until the end of May for the first crop cycle.This encouraged a lot of people to start producing tomatoes, which in turn, brought down tomato prices," Valentin continued. "The consumer market also changed a lot in the last few years. In the past, the biggest focus when choosing tomato varieties was resistance and shelf life, and recently there has been a shift to flavour and taste. In addition to the traditional red tomato; cherry, pink and yellow tomatoes are becoming more popular and offers stable prices for growers." Source - http://www.freshplaza.com


USA - Precipitation Risk Management for Annual Forages

Planting annual forages following a primary crop or specifically for feed can provide a number of benefits, including ground cover and forage resources for livestock. One of the main risks with this production practice, especially in a non-irrigated field, is variable precipitation and soil moisture conditions. The Annual Forage Insurance Plan, available in Nebraska from the USDA – Risk Management Agency (RMA), is one tool available to crop and livestock producers to help mitigate this risk. ANNUAL FORAGE INSURANCE PLAN The Annual Forage Insurance Plan coverage is for annual forages seeded for use as livestock feed or fodder. This includes annual forage plants seeded for grazing, haying, grazing/haying, grain/grazing, green chop, grazing/green chop, or silage. The Annual Forage Insurance Plan now includes four growing seasons that cover the entire year. Growing Season 1, Planting Dates: Jul 16 – Oct 15, Rainfall coverage available from Sep 1 - Mar 31 Growing Season 2, Planting Dates: Oct 16 – Jan 15, Rainfall coverage available from Dec 1 - Jun 30 Growing Season 3, Planting Dates: Jan 16 – Apr 15, Rainfall coverage available from Mar 1 - Sep 30 Growing Season 4, Planting Dates: Apr 16 – Jul 15, Rainfall coverage available from June 1 - Nov 30 The sign-up deadline for all of these growing seasons is July 15 each year so producers interested in obtaining this insurance should contact their crop insurance agent in early summer to see what they need to do to get the coverage in place and what it might cost them. The Annual Forage Insurance Plan coverage is based off of precipitation index data provided by the National Oceanic and Atmospheric Administration Climate Prediction Center (NOAA CPC). Producers can insure from 70 percent to 90 percent of the Expected Grid Index precipitation across a series of two-month intervals spanning the coverage period for each growing season. Both irrigated and non-irrigated acres are insurable. Each county in Nebraska has a County Base Value determined by the RMA that represents its annual forage productive value regardless of production method. Annual Forage Insurance Plan premium costs will vary depending upon the coverage selected. Producers interested in using the plan are encouraged to access the decision support tool on the RMA website to explore various coverage options, premium costs, and performance data based on historical rainfall indices. Premium costs are subsidized from 51 percent to 59 percent depending upon coverage level selection. Catastrophic (CAT) coverage is available for the Annual Forage Insurance Plan. In general, it is hard to justify purchasing it unless a person has a lot of acres to cover within a particular county and is only protecting against a prolonged dry period. CAT coverage is fixed at 65 percent coverage on precipitation for the entire growing season, as one six- to seven-month interval. The productivity factor is fixed at 45 percent. SUMMARY Soil moisture at the time of planting annual forages as well as precipitation during the growing season is one of the primary drivers in the expected yield. Rainfall during germination and early growth is key for annual forages that require shallow planting because of small seed size. Adequate rainfall during the periods when these annual forages are growing rapidly is also critical. Producers utilizing the plan and choosing which two-month intervals to insure should evaluate how soil moisture and timing of precipitation would impact the annual forage crop that is being insured. Maximizing insurance coverage in the two-month intervals when precipitation would have the greatest impact on forage production would be logical. For producers considering utilizing the Annual Forage Insurance Plan in Nebraska, one of the greatest challenges in using the product is the timing of the sign-up period for purchasing the insurance. The deadline for buying the insurance is July 15 for the next crop year. Many producers who plant annual forages especially in the spring and summer will often have not identified the specific number of acres or crops that they plan to plant this far in advance. Producers planting annual forages in the spring and summer who have long-term cropping plans will be best positioned to utilize this risk management tool. Source - https://www.drovers.com
